Products of particlelike representations of the homogeneous Lorentz group are used to construct the degrees of spin angular momentum of a composite system of protons and neutrons. If a canonical labeling system is adopted for each state, a shell structure emerges. Furthermore the use of the Dirac ring ensures that the spin is characterized by half-angles in accord with the neutron-rotation experiment. It is possible to construct a Clebsch-Gordan decomposition to reduce a state of complex angular momentum into simpler states (...) which can be identified with α and β particles, multipole operators, etc. Finally, ground-state energy levels are calculated for all the even-even nuclei by using a differentiable manifold that is spin-graded and gauge-invariant by construction. It is shown that this manifold is Grassmann. (shrink)

This is a summary of “Toward a Global Media Ethics: Theoretical Perspectives,” which appeared in Ecquid Novi: African Journalism Studies , 29(2), 2008, 135-172. The article was written by Clifford G. Christians, University of Illinois at Urbana-Champaign; Shakuntala Rao, State University of New York-Plattsburgh; Stephen J. A. Ward, University of Wisconsin-Madison; and Herman Wasserman, University of Sheffield. It was the result of a workshop on global media ethics by the article's authors hosted by the Stellenbosch Institute for Advanced Study (STIAS) (...) at the University of Stellenbosch, South Africa. The authors brought to the discussion the different perspectives of contractualism, communitarianism, and critical theory. The intention of the summary is to the draw the attention of scholars and ethicists outside the readership of Ecquid Novi to this leading-edge theoretical work. It is hoped the summary will stimulate comment and further work in global media ethics. The summary is not intended to replace the original article. Readers should consult the original for the full argument. (shrink)

As it is known, there is no rule satisfying Additivity in the complete domain of bankruptcy problems. This paper proposes a notion of partial Additivity in this context, to be called µ-additivity. We find that µ-additivity, together with two quite compelling axioms, anonymity and continuity, identify the Minimal Overlap rule, introduced by Neill (1982).

In lieu of an abstract, here is a brief excerpt of the content:Maps for the Classical World: Where Do We Go from Here?Richard TalbertThe apa’s classical atlas project was conceived as the means to an end, and rightly so. Good maps were taken to be vital tools for understanding ancient history and culture at any level, and the ones available in the early 1980s were altogether woefully inadequate. The project was designed to fill this void by preparing a comprehensive atlas (...) for publication in the not-too-distant future.To make a definitive claim at this moment that the target of publication by the end of 1999 will be met must still rank as hubris. Without doubt, however, the odds have increasingly shifted over the past few years in favor of timely completion. As everyone knows, the problems of designing, funding, and developing any ambitious collaborative project are immense, and the atlas has been handed its full share of such difficulties and more. Yet gradually the difficulties seem to have been surmounted, and the project—at present, anyway—remains resolutely on schedule, as much to the surprise of its Director as to everyone else.As the odds have shifted, so, too, has my own perception of the project as an end. To be sure, the maps appearing in the atlas volume will offer the intended comprehensive vision of the physical and cultural landscape of classical antiquity that has been so seriously lacking since Carl Müller provided the last one for William Smith’s Atlas of Ancient Geography in the 1870s. Further gains are assured, too. In particular, to accommodate different needs, it should certainly prove practical to issue the maps in a variety of alternative formats—in sets of loose sheets, for example (with or without cultural data marked on the ancient physical landscape), as wall-maps, slides, digitized images, even a reduced-size textbook atlas. One way or another, these maps have the potential to exert a formative influence on our perception of the classical landscape for many decades to come.Even at the current stage, well before publication, the Atlas Project [End Page 323] has already stimulated fresh attention to cartography: this has grown without any special effort on the project’s part. Most notably, colleagues have become aware that there is now for the first time somewhere to which they can turn as they seek out suitable cartographic materials and design for their research or publications or field survey.Classical studies worldwide would benefit immensely if that “somewhere” were to be made a permanent “center,” established around the same time as the publication of the Atlas of the Greek and Roman World. In the creation of the atlas, both materials and expertise have been accumulated, which it would be irresponsible simply to abandon. The materials cover a wide range—from elements for all the aeronautical charts forming the physical bases for the atlas maps, to copies of older rare maps devoted to classical antiquity.Such maps (and whatever text accompanies them) are by no means necessarily all about to be rendered obsolete by the atlas. The French “archaeological atlases” of Algeria and Tunisia, for example, were compiled by the Brigades Topographiques in the late nineteenth and early twentieth centuries at scales as generous as 1 : 50,000, whereas the atlas limits itself to 1 : 500,000 in this region (and the area covered by one map at 1 : 500,000 corresponds to literally dozens at 1 : 50,000). Thus for any study with a close focus on Algeria or Tunisia, these French series remain indispensable, although the Tunisian one, with its two editions, is exceptionally rare and hard to obtain. Typically, the few libraries that hold this material have bound the original loose sheet maps into books (rendering it impossible to use the sheets individually), and for obvious reasons, they are not willing lenders. The Atlas Project, I imagine, has been the first to photograph the printed map sheets onto transparent plastic positives. These are sturdy, dimensionally stable, and immune from the fading and deterioration of paper; in addition, when they are laid on top of other maps, everything underneath remains visible.Examples of further cartographic materials for the classical world which will continue to...
